When people talk about cloud computing, they are more than likely talking about Software as a Service (SaaS) technology.
From SaaS CRM to SaaS ERP, these applications have caused major disruption in IT in recent years. More than half of respondents to the TechTarget 2012 IT Priorities survey said they are using it. But anyone with an eye for IT doesn't need a survey to know that SaaS is here to stay.
SearchCloudApplications.com's one-page guide to SaaS Applications and Strategy will serve as a repository for critical SaaS knowledge. For the uninitiated, the guide begins with a series of definitions and a glossary of key terms before moving on to cover key issues and deliver expert advice.
Perhaps no issue is more crucial to understanding SaaS than the debate between choosing it or on-premises software. There are many questions a diligent IT manager should ask of any cloud provider and these articles convey them, along with a description of just how disruptive SaaS has been.
Once the choice is made to move to the cloud, the next logical question is what happens with the data? Cloud integration has become a major issue, whether it's integration between cloud applications, between a cloud app and an on-premises data center, or between a cloud app and on-premises software. Learning how to approach cloud integration is key for success with SaaS.
The rest of our guide includes an expert drilldown into more nuanced SaaS technology issues, an overview of service-level agreements and the potential traps therein for enterprises, and a video guide from consultant Jeff Kaplan, managing director of THINKstrategies in Wellesley, Mass.
